The guitarist in my post-metal band used to use hollowbodies (specifically very jazzy guitars), and we found that although there can be a lot of feedback, a good EQ pedal can be used to tame it. A good quality head works as well, crappy amps in practice rooms didn't help us at all, but his Dual Terror was fine with it.

The feedback could be pretty useful at times, there were a couple of notes on the guitar that would basically sustain infinitely if you held them down and allowed feedback to happen. Only about two notes, but it was still pretty cool.

Don't forget that a noise gate will help a lot to tame feedback. Almost any guitar will start to have feedback issues with most levels of gain people use for metal, so a noise gate is essential for basically anyone anyway.
